Benn Robinson is hoping to give Australia a major fillip prior to their Tri-Nations showdown with South Africa on July 24 as he prepares for a long-awaited return to action.

The Waratahs loose-head has played an active part in training this week after recovering from a fractured forearm sustained while on Super 14 duty in May. Robinson was sorely missed during the Wallabies' June Tests, when their rookie front-row was put to the sword by England in Perth.

He will turn out for Eastwood in a Shute Shield match on Saturday, going up against West Harbour's former Wallaby prop, Rodney Blake.

"I think I'm playing against Rodney Blake," he told AAP. "He's around 135 kilos, so it's going to be a big test for me, coming back to scrummaging."

Nevertheless, Robinson has confidence in his arm after he and hooker Stephen Moore, just back from a broken jaw, were treated to plenty of rough and tumble during training with the Wallabies.

"This week is a real tester for us, he [Moore] has got a few knocks on the jaw already and I've got a fair whack on my arm," Robinson said. "It's just about getting confidence back in your arm and you achieve that through a few bumps and bruises."
